I tried the web version a couple of weeks ago and the Android version just now, and both ran fine for me (except that the Android ‘back’ button didn’t let me quit).
The game looks lovely. You’ll be getting work as an artist soon at this rate. 
The health and power numbers on the ‘stats’ screen didn’t seem to change, and the ‘use’ button for the battery didn’t do anything (are the batteries used automatically?).
It wasn’t at all clear to me what the ‘down stairs’ tile was until I stood on it - and then it was too late. It feels wrong not to be able to go back up a level (it seemed more natural for Yore’s dungeons) and, as Kevin says above, it made the first mission impossible to complete.
I wonder whether the game isn’t maybe following Yore’s formula too closely. Random dungeons don’t seem so natural in space. Maybe if the dungeon generation added a bit of symmetry…? And a bit more organisation between the enemies (the smart ones at least) like setting off alarms and running towards rooms where there is fighting…?
I like the sound of the space exploration aspects you’re adding. The current cut-scene of simply flying to a planet felt like a missed opportunity.
And yes, the game needs Titans. 
I vote for a Carry On-themed roguelike called Legends of Phwoar! ;D
